METHOD OF PREPARATION OF REVERSE EMULSION FOR PROCESS OF KILLING AND INTENSIFICATION OF OIL AND GAS WELLS Russian patent published in 2009 - IPC C09K8/42 C09K8/72 

FIELD: mining.

SUBSTANCE: method of preparing reverse hydrophobic emulsion for treatment of bottomhole zone of reservoir consists in mixing disperse medium, oil- soluble emulsifier and disperse phase in capacity of disperser case; oil hydrocarbons of paraffin row are used as disperse medium; water solution of hydrochloric acid, or water solution of calcium chloride, or sodium chloride, or zinc chloride are used as disperse phase at following ratio of components, vol %; oil soluble emulsifier 1-5, said disperse medium 27-45, said disperse phase - the rest; components are introduced into said capacity simultaneously and are mixed with mixer of blade type interacting with whole volume of mixture at angular rate 2000 rev/min; blades of mixer are made out of steel sheet; holes are arranged on one blade with set-off relative to arrangement of holes on another blade; gap between blades and internal surface of said capacity is 2-4 mm.

EFFECT: simplification of method of preparing reverse emulsion and improved properties of reverse emulsion, also increased electrical and thermal stability.
